It was both of your fifth years at Hogwarts, you proposed to Draco about 2 months ago, and he reciprocated your feelings, a few days after you proposed, he asked you to be your boyfriend, and you accepted.

Draco watched you from a distance talking to Ginny Weasley and he became "jealous", then he approached you and said

"Rry!!!"

He gave you a hug and then looked at Ginny.

You're taller than Draco (because it's Harco not Drarry.)
